RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
There is possibility to set initcwnd and initrwnd options via ip command but there is no way to perform this using the nmcli.

Example of ip command:
ip route add default via x.x.x.x dev ethX proto static initcwnd X

Would it be applicable to add this feature to nmcli settings ?

Version-Release number of selected component (if applicable): 
All versions of NetworkManager

Actual results: No way of setting initcwnd and initrwnd via nmcli

Expected results: Be able to configure those values using nmcli

Thank you

As you say, you currently can only configure basic attributes of a route.
E.g. no multi-path or policy-routing.





Current workaround:
===================


configure those routes in initscripts file
  /etc/sysconfig/network-scripts/rule-$NAME
  /etc/sysconfig/network-scripts/rule6-$NAME



to make this work also:

- ensure that the NetworkManager connection is handled via ifcfg-rh plugin (by default on RHEL). Basically, there should be a corresponding /etc/sysconfig/network-scripts/ifcfg-$NAME file for your connection.

- ensure dispatcher is enabled (by default on RHEL)
  $ systemctl status NetworkManager-dispatcher

- ensure NetworkManger-config-routing-rules package is installed (by default on RHEL). In rhel-7.3 this package will be renamed to NetworkManager-dispatcher-routing-rules. This package provides /etc/NetworkManager/dispatcher.d/10-ifcfg-rh-routes.sh which will apply the routes from the rule- file above.

Bug 1373698 is also about adding native support for route options in NM. I'm closing this as a duplicate.
